Assembler is a low-level language that is about as close as you can get to coding directly in machine language. Since it operates directly with registers and memory, it is rather platform-dependent but (given proper coding) has the benefit of usually running faster than an equivalent module written in a higher level language.
COBOL is a high-level language that has syntax similar to natural language.
